Filter by:A reduction in peak heart rate (HR) and suppressed HR response during exercise is highly prevalent in obese populations. This phenomenon is also known as chronotropic incompetence (CI). In adult obese individuals, CI is independently related to elevated risk for major adverse cardiovascular events and premature death. Despite the established association between CI and prognosis in adult populations, the prognostic relevance of CI in adolescents with obesity has however deserved no attention, but is important. CI during exercise testing may indicate various, yet undetected anomalies, such as altered blood catecholamine and/or potassium concentrations during exercise, structural myocardial abnormalities or ventricular stiffness, impaired baroreflex sensitivity and cardiovascular autonomic dysfunction, atherosclerosis, or cardiac electrophysiological anomalies, which all have been detected in obese children and adolescents. However, whether CI during exercise testing may be a sensitive and specific indicator for these anomalies in obese adolescents has not been studied yet. In addition, the exact physiology behind obesity and development of heart disease remains to be studied in greater detail in obese adolescents. In this project, we examine the prevalence of CI (during maximal cardiopulmonary exercise testing, CPET) in 60 obese adolescents (aged 12-16 years) vs. 60 lean adolescents, and study the association between CI and changes in CPET parameters, lactate, catecholamine and potassium concentrations during CPET, biochemical variables, and cardiac electrophysiology (by ECG recording). In addition, the relation between CI and cardiac function (echocardiography) will be examined in a subgroup (29 lean and 29 obese) of these adolescents. In this regard, the diagnostic value of HR (responses) during maximal exercise testing will be clarified in obese adolescents, and the physiology behind the elevated risk for heart disease in obese adolescents can be explored.
A randomized, open-label study with antacid-control will be performed over 48 hours period by continuous pH impedance and bravo capsule monitoring. Asymptomatic obese patients will be separated into either groups according to alginate antacid group [Gaviscon Advance (GA)®, Reckitt Benckiser, UK] and non antacid alginate group [simple antacid]. Both groups will be studied for 48 hours using the ambulatory wireless capsule and pH impedance. Participants according to their group will take either alginate antcid [Gaviscon Advance (GA)®, Reckitt Benckiser, UK] or non alginate antacid [simple antacid] which has equivalent strength of antacid after taking late night standardised meals.
Transdisciplinary practice-based action research project that aims to develop innovative cognitive-behavioral interventions to empower adolescents, through increased and interactive contact between adolescent and multidisciplinary healthcare team. Project born from the discussion with trans-territorial stakeholders (health professionals and school communities), in the absence of an integrated, creative and dynamic strategy of overweight prevention and promotion of salutogenic behaviors in adolescents. The polytechnics of Leiria, Santarém and Castelo Branco are co-promotors of this project, as well as Município de Leiria (City Council), key partners in the development and implementation of the intervention program. It is expected the partnership with ARS-Centro. The main goal is the development, implementation and evaluation of a program for the promotion of healthy behaviors and prevention of obesity in adolescence, based on e-therapy and sustained by the case management methodology.
It has been established that greater amounts of vigorous intensity physical activity lead to improved health outcomes. Interestingly, the response of biologically active substances, called myokines, differs according to exercise intensity. As such, the current study aims to compare the difference in the response to irisin according to different exercise intensities in both normal weight subjects and individuals living with obesity. This study will compare continuous moderate intensity physical activity to high intensity physical activity against a control condition. Furthermore, this study will determine whether differences in exercise intensity are associated with better insulin sensitivity.
The primary aims were to assess community capacity to develop, implement, and sustain a childhood obesity reduction initiative in the health-disparate Dan River Region as well as to pilot test iChoose to determine the potential reach (i.e., proportion of target population & representativeness), effectiveness (i.e., changes in child BMI z-scores over a 6 month period), feasibility (i.e., the degree to which the intervention can be adopted, implemented, and sustained as intended) and cost (i.e., resource and staffing costs) of the newly developed intervention.
The study is a single-blind, randomised crossover study, investigating how a high glycaemic potato affects satiety in humans compared to a low glycaemic potato. This is done to shed further light on the discussion about whether potatoes with a high glycaemic index increases the risk of overweight and obesity and thus indirectly type 2 diabetes and cardiovascular disease.
Investigators examined the associations between SSS, energy balance, food intake and changes in body composition following a high calorie lunch for 2 weeks.
Excess weight or obesity is associated with an increased risk of health disorders: high blood pressure, diabetes, cardiovascular risks, dyslipidemia and sleep apneas. During pregnancy in obese women, the risk of preeclampsia increases by three and the risk of fetal death in utero by five. Snoring and Obstructive sleep apnea (OSA) may be associated with increased risk of adverse pregnancy outcomes, including maternal cardio pulmonary status, fetal heart rate and fetal acidosis-basis status by recurrent upper-airway obstruction, hypoventilation, and intermittent nocturnal hypoxia. Reports in pregnancy have identified in association with OSA and preeclampsia, intrauterine growth restriction and stillbirth. The prevalence of OSA among women is estimated to be 2-5%, but it remains underdiagnosed during pregnancy. In sleep apnea syndrome, a few data have shown better pregnancy and fetal outcome with the use continuous positive airway pressure (CPAP) therapy. the hypothesis is in obese pregnant women that there could be a significant association between sleep apnea syndrome and hypertensive disorders, preeclampsia and adverse fetal outcomes This is a prospective study of Women with a body mass index of 35 kg.m2 or greater. The aim of this study is to determinate the prevalence of sleep apnea syndrome in obese pregnant women and the benefit of CPAP on the maternal and fetal outcome.
Summary Description The goal of this intervention study is to test how well does a weight management curriculum work in virtual group-based medical visits (telehealth) for the treatment of adolescents with obesity. The main questions it aims to answer are: - How well does providing group-based medical care for obesity using telehealth work? - How doable is it to provide virtual group-based health education visits with adolescent patients? - Are the group-based health education visits similar, or better than the traditional in-person clinic visits? Participants will be asked to: - Complete surveys, do bloodwork, and physical measurements like blood pressure, height and weight before the study activities start and after completing the study activities - Participate in study activities such as attending 12 virtual sessions lasting 60 minutes each, every other week, over a period of 6 months - Join group learning and discussions of topics like nutrition, barriers to physical activity, and mental health with various facilitators like a medical doctor, dietitian, psychologist, and physical therapist - Take part of in brief individual coaching sessions over email or over the phone Researchers will compare the virtual group-based medical visits to the traditional in-person weight management clinic visits (EMPOWER Weight Management Clinic) to see if the study can be another option in the treatment of adolescents with obesity.
This is a large and comprehensively phenotyped cohort with fasting glycaemia where the predictive value of body composition and anthropometric measures of total and central fat distribution for postprandial carbohydrate intolerance are studied.
